…is works? If two thoughts try to enter the conscious mind at precisely the same time it results in competitive blockade. Thus, not even these two but even other thoughts can't enter the conscious mind leaving it blank giving us false peace. This also abolishes all thoughts, emotions, feelings and movements giving us false control. Sigmund Freud used this principle to give relief his patients relief from mental problems. Even now Psychoanalysis is believed to be scientific even though the effect (abnormal behavior) disappears in the presence of the cause (childhood trauma) which is scientifically paradoxical. Finding the cause of the present problem in the past: Normally, this blockade is a accident and immediately the dominant thought succeeds in entering the conscious mind. However, the blockade can be continued as long as we have voluntary force. When voluntary force is depleted we allow crossing over of emotions. We transfer the emotion of a socially unacceptable thought into a socially acceptable thought let the socially acceptable thought to manifest as action. If no action is permitted then the thought selected should be such that it can't get converted into an action. It is for this reason that Sigmund Freud used to select a thought from the childhood of the patient that can't get converted into an action. Thus, Psychoanalysis works on the principal of competitive blockade. (MORE)
